They too can be bossy. As far as the shrimp dispute I've heard many different things about the coral banded shrimp. Kinda hit and miss depending on food and tank size I guess. That's why I got a cleaner shrimp. He is AWESOME and doesn't pick on anything or anyone in my tank. I also have peppermint shrimp and they are fine together.

Same thing, there is an orchid dotty back that is supposed to be nicer that looks exactly the same except it has a line through its eye, though I have never seen the orchid dotty back for sale anywhere.

I also had a bad coral banded it was fine when it was small but it got pretty big after a year a finally caught a fish also had a sally lightfoot catch and eat a fish they have big pinchers for a reason not decoration lol

Great imput! It sounds like our purple dottyback could be on the aggressive side to other fish that we may purchase in the future. He seems fine right now with the clowns and chromis. We'd like to get 2 more of the blue/green chromis, for a small school and a pair of cleaner shrimp.

Do you have suggestions for other future reef safe fish purchases that the purple dottyback won't bother?

It's hard to say, I added a few fish after my dotty back/basslet , he terrorized a six line wrasse, but left a pair of clowns and the purple fire goby alone.
And if the dotty back is fairly new itself, adding new fish might go better. He may not have a chance to figure out and claim the tank as his yet if he's been in there for less than a month.
